I know that one can limit the number of OUTGOING recipients in the SMTP Advance Max Number recipients per message section, but can one limit the number of INCOMING recipients on your server in a single email, to help prevent dictionary attacks?
If not, is there a way to block an IP or email immediately once x number of invalid users are attempted to be sent to in a single email?
